django Manytomany字段插入空数据

Question

模型

class Enrollee(TimeStampedModel):

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, verbose_name=_('id'))

    first_name = models.CharField(max_length=60, verbose_name=_('first name'))

    dependents = models.ManyToManyField(to=Dependant, blank=True, verbose_name=_('dependents'))

class Dependant(TimeStampedModel):

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, verbose_name=_('id'))

    first_name = models.CharField(max_length=60, verbose_name=_('first name'))

看法

class EnrolleeViewSet(viewsets.ModelViewSet):

    queryset = models.Enrollee.objects.all()

    serializer_class = serializers.EnrolleeSerializer

    filter_class = filters.EnrolleeFilter

序列化器

class EnrolleeSerializer(DynamicFieldsMixin, DynamicFieldsModelSerializer):

    dependents = DependantSerializer(many=True, required=False)

    def create(self, validated_data):

        dependant_data = validated_data.pop('dependents')

        enrollee = models.Enrollee.objects.create(**validated_data)

        for dependant in dependant_data:

            models.Dependant.objects.create(**dependant)

        return enrollee

class Meta:

    model = models.Enrollee

    fields = '__all__'

错误：

  {

  "first_name": "hmo1",

  "dependents": [],

  }

这意味着家属没有插入

在这里，我尝试为我的家属发送嵌套数据（ManyToManyField）但是，在插入数据时出现上述错误。

我们有什么办法可以实现这一目标吗？

{

  "first_name":"soubhagya",

  "dependents" : [

     {

       "first_name":"soubhagya"

     }

  ]

}

以上是我使用 post 方法发送的数据。

请看一看

def create(self, validated_data):    dependant_data = validated_data.pop('dependents')    enrollee = models.Enrollee.objects.create(**validated_data)    for dependant in dependant_data:        obj = models.Dependant.objects.create(**dependant)        enrollee.dependents.add(obj)    enrollee.save()    return enrollee
